Why Companies Hire Me

I'm the person teams call when their iOS/AR projects are on fire

With 8+ years of iOS development across 10+ companies and 50+ applications, I specialize in diagnosing and fixing complex technical problems in ARKit, CoreML, and visionOS applications. I've helped companies rescue failing apps, optimize performance, and ship products that seemed impossible.

How I Work

Diagnostic Obsession

I don't stop until I find the root cause. Surface-level fixes aren't fixes — they're time bombs waiting to go off.

Clear Communication

Technical reports written in plain English. You'll understand exactly what's wrong and how to fix it.

Fast Turnaround

Most audits completed in 3-5 days. I know your launch timeline doesn't wait.

No BS Policy

If I can't help, I'll tell you immediately and point you to someone who can. Your time is valuable.

What I Don't Do

  • Build apps from scratch
  • Ongoing maintenance contracts
  • Work without clear requirements
  • Projects outside iOS/AR/ML
  • Design or UI work

What I Do Best

  • Fix critical production issues
  • Optimize struggling applications
  • Debug complex ARKit/ML problems
  • Audit codebases before launches
  • Guide technical architecture decisions
  • Rescue failed projects
